Since moral differences are expressions of differences in reproductive strategy,

Since moral differences are expressions of differences in reproductive strategy, and since moral intuitions are reflections of those differences, and since we appear out of necessity to be morally blind to competing sets of differences, then moral intuition tells us noting whatsoever. We can agree to cooperate on means, but we cannot agree to cooperate on ends. In the end, we are competing, and the byproduct of our reproductive cooperation is generally beneficial for all. Government can be used to transfer the benefits between classes (as it has been for 150 years) at the expense of dysgenic reproduction.

The value of property rights (propertarianism) is that it reduces all statements to non-moral form.

Property is the logic of cooperation.
